  • Provide the achievement of strictly linear polarization of laser radiation
  • Utilise the polarization which occurs on reflection from a plane surface
  • Rs/Tp>99.5/95.0% for Standard Thin Film Laser Polarizers
  • Rs/Tp>99.5/99.0% for High Transmission Thin Film Laser Polarizers
  • Tp>98%, Ts<0.1% for Thin Film Polarizers with High Extinction Ratio
  • >200:1 exctinction ratio for standard and high transmission polarizers
  • >1000:1 exctinction ratio for polarizers with high extinction ratio (HE series)

Thin Film Polarizers are used in high energy lasers. They can be used as extracavity attenuators for Nd:YAG laser fundamental and its harmonics or intracavity Q-switch hold-off polarizers. The most efficient way to use thin film polarizers is at Brewster angle – 56°±2° with minimal losses. Typical polarization ratio Tp/Ts is 200:1. We provide Thin Film Laser Polarizers with Tp>99% under customer request.
